There is no action (or barely any) at all on the keys. But, I find typing on it to be MUCH more difficult than the first one. I end up hitting many keys twice because there is no tactile feel. But, I have yet to notice any dust (the first device had dust in it after 18 days). Part of me wishes that I didn't return my first 8700 as I liked typing on it so much more. It's a trade-off, I guess: solid key action and dust or no dust and slower typing. Lesson: be careful what you wish for.
